I'm using a carbide insert threading tool.





The actual cutting of the thread seems fine, just a bit of a faff setting up change gears if one wants to change between different thread pitches or go back to a longitudinal feed.

Both brass and stainless can cause galvanic corrosion with aluminium, not sure if brass is significantly worse or not. Was probably going to use a smidge of anti seize compound whatever material I end up using...

Do you have a good source of Info for final outer diameter and depth of cut for threading?

Edit - so I found this resource http://www.roymech.co.uk/Useful_Tabl...hread_tol.html

So if I understand correctly, for example with this m5x0.8 thread I need here:

- Turn the portion to be threaded to 5mm.

- Thread with 0.8mm pitch until a depth of 0.69mm

- Skim across to reduce the outer diameter to say 4.8mm

Is that the correct process?
